No picture on tv, nor sound? Maybe your TV doesn't have picture because you forgot to turn it on. All you need to do is to turn it on and the TV should start working, i.e. you should see picture on the screen.
If your LG TV doesn't have picture and you are not sure what course of action to take, contact LG's customer service, by dialling the following number: +1 800-243-0000.
Another way to contact them is by paying them a visit through their website (click here to visit it).
